Penta-light uploaded to Thingiverse

Designed in Blender just for fun, it’s a small 5 Led-diode lamp, that is powered by 3 AAA batteries. What I like about pentagons is that it does not matter from what angle you see the iluminated object, there are always 3 lights to see.

With the 100 Ohm resistances the light should stay about 30 hours long (depending of what rechargable batteries are used)
